Title: Pulse laser condensing device of wavelength conversion type
Inventor: KAMEYAMA TAKAHARU
IPC: H01S3/101
Filed: 1983-04-26
Abstract: PURPOSE:To perform focusing of a short-wavelength laser light, whose wavelength is converted by a wavelength converter, automatically only with focusing of infrared laser rays of a pulse laser device by utilizing the fact that wavelengths of both lights are known. CONSTITUTION:In the state where a wavelength converter 7 is removed from the optical path, infrared laser rays for laser device alignment in a pulse laser device 11 is reflected by mirrors 4 and 5 and is focused on a target 10. The reflected light is received by a two-wavelength optical axis and focus error detector 58 to detect the variance of the beam optical axis, the angle of spread of the beam, and the positional variance of a condenser lens 3 and a target 10, and only angles of mirrors 4 and 5 and the position of the lens 3 are adjusted to adjust automatically mirrors and the lens with a correction quantity (calculated value) based on the difference of wavelength between the reflected light and infrared laser rays because the reflected light is the short-wavelength laser light. If a minute error exists still by insertion of the wavelength converter 7, they are further adjusted automatically.

Title: Mold
Inventor: IGUCHI ASAO
IPC: B29L11/00
Filed: 1984-04-12
Abstract: PURPOSE:To largely improve the rapidity and stability of regulating the temperature of a mold by constructing a thermal medium transport passage in the mold in a heat insulating structure, and alleviating the heat loss in the course of the thermal medium transport. CONSTITUTION:Thermal medium is transported through the interior of a thermal medium transporting member 22 provided with a heat insulating layer while the medium supplied to a mold arrives from supply ports 18, 19 into heat exchangers 3, 4 near a cavity and a gate.

Title: Circuit for discriminating presence or absence of intermittent pulse
Inventor: NARITA TAKAHITO
IPC: H03K5/153
Filed: 1986-03-31
Abstract: PURPOSE:To eliminate the effect by a periodic disturbing pulse or a random pulse and to eliminate the need for highly accurate adjustment of a time constant by using three monostable multivibrators and bringing the trigger function and time constant of each multivibrator into a specific relation. CONSTITUTION:In the clog detection by a rotary magentic head, the input continues for a consecutive period Tp at an interval or P and stops for a stop period of Tt-Tp. Further, a control signal CTL is also mixed. Since the lst monostable multivibrator 4 has a time constant longer than the period P of the pulse and sufficiently shorter than the stop period Tt-Tp, rises by a pulse P or a positive pulse of the control signal CTL and descends after the time constant after the input is lost. The 2nd monostable multivibrator 5 has a time constant slightly shorter the period Tp and sufficiently longer than the period P and the time width of the positive pulse of the conrol signal CTL, and the 3rd monostable multivibrator 6 has a time constant longer than the period Tt and shorter than 2Tt. Thus, in scanning the 2nd luminance signal Yb, if any clog takes place, the missing of the pulse group is detected.
